| titleOfInvention | Method of development of heterogeneous-layer oil deposits |
| abstract | FIELD: oil-and-gas industry. n SUBSTANCE: proposed method comprises injection of working agent via injection wells, extraction of oil via production wells, injection of sealing agent based on sodium silicate and acid into injection or production wells, holding the welds for a day and making them operate. Prior to injecting said sealing agent into bed, water-slug is injected in amount inhibiting the mixing of bed water with sealing agent till its gelation but not smaller than one volume of tubing. Holding is performed after injection of said agent into the bed. Sealing agent is composed by gel-like compound of the following composition, wt %: sodium silicate - 3-8, sulfonic acid - 0.38-1.5, chromium acetate - 0.35-0.9, monoethanol-amine - 0.35-0.9. n EFFECT: higher efficiency of sealing. n 2 ex, 1 dwg |
